The Silica Sand Company opened in 1905 a glass sandquarry at Craddock on the Weston and Pickens branch ofthe Baltimore and Ohio railroad up the Buckhannon river inUpshur County, 47 miles from Weston or 4 miles northwest ofPickens. The equipment includes an Austin No. 5 rotary crusher,8-foot wet pan, five washing screw conveyors. The sand isdried in a Cummer drier, 22 feet long, and screened through 8and 14 mesh screens. 28 men are employed, and the dailycapacity is 120 to 150 tons of glass sand and 15 tons of peb-bles and coarse gravel used for concrete. The storage ca-pacity is about 30 cars, the sand being held in a steel tank of400 tons capacity, and bins holding 80 tons with a large floorspace for the wet sand.
